Node.js security covers vulnerabilities, dependency risks, and runtime defenses that can affect server-side applications and their data.

Background for this topic.
Node.js is an open-source, cross-platform runtime that executes JavaScript outside a web browser, using Google’s V8 engine. Its event-driven, non-blocking input/output model is widely used for web servers, APIs, command-line tools, and backend services. The runtime is not itself an application framework; security outcomes depend substantially on the code and modules running within it.
Security concerns include vulnerabilities in the Node.js runtime, insecure application logic such as injection or server-side request forgery, and risks from the large npm dependency ecosystem. Malicious or compromised packages, unsafe install scripts, transitive dependencies, and prototype-pollution flaws can expand an application’s attack surface. Practitioners should track runtime and package advisories, use lockfiles and dependency review, restrict package-install and process permissions where practical, validate untrusted input, and protect credentials and session data. During incidents, dependency inventories and build records help determine whether a vulnerable module or runtime was deployed.

Mini Shai-Hulud caught spreading credential-stealing malware The wave of supply chain attacks aimed at security and developer tools has washed up more victims, namely SAP and Intercom npm packages, plus the lightning PyPI package.…
Plus, the payload references 'TeamPCP/LiteLLM method' Yet another npm supply-chain attack is worming its way through compromised packages, stealing secrets and sensitive data as it moves through developers' environments, and it shares significant overlap with the open source infections attributed to TeamPCP last month.…
Hijacked maintainer account let attackers slip cross-platform trojan into 100M-downloads-a-week Axios Updated One of npm's most widely used HTTP client libraries briefly became a malware delivery vehicle after attackers hijacked a maintainer's account and slipped a remote-access trojan (RAT) into two seemingly legitimate axios releases, in what's being described as "one of the most impactful npm supply chain attacks on record."…
4K unintended installs in very odd supply chain attack Someone compromised open source AI coding assistant Cline CLI's npm package earlier this week in an odd supply chain attack that secretly installed OpenClaw on developers' machines without their knowledge. …
And it's especially dangerous because the code works A malicious npm package with more than 56,000 downloads masquerades as a working WhatsApp Web API library, and then it steals messages, harvests credentials and contacts, and hijacks users' WhatsApp accounts.…
Automation flaw in CI/CD workflow let a bad pull request unleash worm into npm PostHog says the Shai-Hulud 2.0 npm worm compromise was "the largest and most impactful security incident" it's ever experienced after attackers slipped malicious releases into its JavaScript SDKs and tried to auto-loot developer credentials.…
Trojanized npm packages spread new variant that executes in pre-install phase, hitting thousands within days A self-propagating malware targeting node package managers (npm) is back for a second round, according to Wiz researchers who say that more than 25,000 developers had their secrets compromised within three days.…
Amazon spilled the TEA Yet another supply chain attack has hit the npm registry in what Amazon describes as "one of the largest package flooding incidents in open source registry history" - but with a twist. Instead of injecting credential-stealing code or ransomware into the packages, this one is a token farming campaign.…
PhantomRaven slipped over a hundred credential-stealing packages into npm A new supply chain attack dubbed PhantomRaven has flooded the npm registry with malicious packages that steal credentials, tokens, and secrets during installation. The packages appear safe when first downloaded, making them particularly difficult for security apps to identify.…
MCP plus open source plus typosquatting … what could possibly go wrong? A fake npm package posing as Postmark's MCP (Model Context Protocol) server silently stole potentially thousands of emails a day by adding a single line of code that secretly copied outgoing messages to an attacker-controlled address.…
Hundreds of compromised packages pulled as registry shifts to 2FA and trusted publishing GitHub, which owns the npm registry for JavaScript packages, says it is tightening security in response to recent attacks.…
